In the present study, effects of heat treatment on microstructures and tensile properties of the cylindrical bars of Ti-48Al-2Cr-2Nb (at.%) alloy with unique layered microstructure consisting of equiaxed γ grains region (γ band) and duplex-like region fabricated by electron beam melting (EBM) were investigated. We found that it is possible to control width of the γ bands (Wγ) by heat treatments at 1100°C and 1190°C. The Wγ increases with decreasing heat treatment temperature. The bars heat-treated at 1190°C exhibit high elongation of 2.9% at room temperature (RT) with maintaining high strength. The RT elongation increases with increasing the Wγ because of increasing deformable regions. In contrast, the RT elongation of the bars decreases with increasing the Wγ when Wγ is very large. This is because the large γ band leads intergranular fracture. These results indicate that there is appropriate width for the γ band to obtain excellent tensile properties at RT.

Abstract Arcam Ti6Al4V ELI (Grade 23) is a titanium-based alloy that is used for the production of additively manufactured components using electron beam melting (EBM). This alloy offers the best all-round performance for a variety of weight reduction applications in aerospace, automotive, and marine equipment. It also has numerous applications in the medical industry. Arcam Ti6Al4V ELI is very similar to Arcam Ti6Al4V, except that Arcam Ti6Al4V ELI contains reduced levels of oxygen, nitrogen, carbon, and iron. These lower interstitials provide improved ductility and better fracture toughness. This datasheet provides information on composition, physical properties, microstructure, hardness, elasticity, and tensile properties. It also includes information on machining and joining.

Abstract FANSTEEL 80 METAL is a columbium-base alloy containing nominally 1% zirconium. It is produced by electron-beam melting which gives it exceptionally high interstitial purity. It is several times stronger than pure columbium at elevated temperature; and this is without sacrificing the ease of fabrication associated with columbium. Fansteel 80 Metal can be fabricated easily at room temperature and high-quality ductile welds are possible. Its applications include nuclear, liquid metal loops and structures for high-temperature environments. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as forming, heat treating, machining, joining, and surface treatment. Filing Code: Cb-10. Producer or source: Fansteel Metallurgical Corporation. Originally published August 1966, revised November 1981.

AbstractMaterials processed by additive manufacturing often exhibit a very fine-scaled microstructures due to high cooling rates in the process. In this study, single-layer surface electron beam melting is used to create very high cooling rates similar to additive manufacturing processes to investigate the resulting microstructure. In the case of Nb-Si-Cr in-situ composites, a nano-scaled eutectic microstructure is beneficial for improving the mechanical and oxidational properties. Fast solidification results in the formation of supersaturated phases of Nbss and Cr2Nb with phase diameters down to 10 nm as well as in the stabilization of the metastable Nb9(Cr,Si)5 phase at room temperature. After processing with different solidification rates, the decomposition of the Nb9(Cr,Si)5 phase has been studied in detail with atom probe microscopy. The stabilization of mixed silicide phases by electron beam melting shows a new pathway for improving hardness and enhancing oxidation resistance of nanostructured eutectic in-situ composites, by which the inherent weaknesses of Nb-Si-Cr can be overcome without further alloying elements.
